Question

Длина участка прямоугольной формы 40м.Его периметр 140м.Найди площадь огорода.

Answer 1

Problem Analysis

We are given the length of a rectangular garden, which is 40 meters, and the perimeter of the garden, which is 140 meters. We need to find the area of the garden.

Solution

To find the area of the garden, we can use the formula: Area = Length x Width.

Let's assume the width of the garden is w meters. Since the garden is rectangular, the perimeter can be calculated as: Perimeter = 2 x (Length + Width).

Given that the length of the garden is 40 meters and the perimeter is 140 meters, we can set up the equation as follows:

140 = 2 x (40 + w)

Simplifying the equation, we get:

140 = 80 + 2w

Subtracting 80 from both sides, we have:

60 = 2w

Dividing both sides by 2, we get:

w = 30

Therefore, the width of the garden is 30 meters.

Now, we can calculate the area of the garden using the formula:

Area = Length x Width

Substituting the values, we have:

Area = 40 x 30 = 1200 square meters

So, the area of the garden is 1200 square meters.

Answer

The area of the rectangular garden is 1200 square meters.
